NUT-LOCK.

Application filed September 1, 1915.

To all whom it may concern:

Be it known that we, CHARLES O. MYERS and llownnn T. Marine, citizens ofthe United States, residing at lilettysburg, in the county of Adams andState of Pennsyl- Vania, have invented certain new and usefulImprovements in Nut-Locks, of which the following is a specification.

This invention comprehends certain new and useful improvements in nutlocks, and relates particularly to improvements on the type of nut lockfor which Letters Patent of the United States, No. 1,1d2,607, wereissued to us June 8, 1915.

its in the already issued patent, the present invention has for itsprimary object a simple, durable and efficient construction of device ofthis character which may be used effectively not only in connection withsplice bars, fish plates, angle bars, spreader or gage bars, or railjoints generally, but for structural bridge work, machinery, and othermetal work, as well as for work which consists partly or wholly of woodand, in fact, in any place where it is desired to prevent the nut fromworking loose on account of the jars or the like to which it issubjected in service.

A further object of the invention is an improved device of this kind,the parts of which are so constructed and arranged that the device beapplied to any bolt and nut, and without mutilating the threads ofeither of them, the device being further so constructed and arrangedthat the nut may be released whenever it is desired to remove the sameand the bolt which. it holds. And the invention also aims to generallyimprove devices of this kind so as to render them more useful andcommercially desirable.

With these and other objects in view, as will more fully appear as thedescription proceeds, the invention consists in certain constructions,arrangements and combinations of the parts that I shall hereinafterfully describe and claim.

For a full understanding of the invention, reference is to be had to thefollowing description and accompanying drawing, in which- Figure 1 is aperspective view showing our not lock applied to a rail. Fig. 2 is afragmentary sectional view, the section being taken approximately on theline 22 of Fig. 1. Fig. 3 is a detail view of the two parts of thedevice separated from each other, and Fig. l is a fragmentary sectionalSpecification of Letters Patent.

Serial No. 48,465.

View illustrating another application of the device hereinafterspecifically referred to.

Corresponding and like parts are referred to in the followingdescription and designated in all of the views of the accompanyingdrawing by like reference characters.

Referring to the dra 'ing, the numeral 1 designates a bolt of anydesired or conventional design or type, the same being shown in thatembodiment of the invention illustrated in Fig. 1, as extending througha rail 2, and the fish plates or angle bars 3 which are applied toopposite faces of the rail.

1- designates the nut which may have any desired number of sides and maybe of any suitable size, or design, according to the work for which itis required.

The improved nut locking device of this present invention includes abase plate 5, which is preferably formed of spring steel or any otherdesirable substance or material of the requisite strength and tenacity,and which is formed within its margin with an opening 6, whereby it mayhe slipped over upon the threaded end of the bolt 1. 9n one edge thebase plate 5 is formed with a preferably pliable flange 7, which isdesigned to extend over and engage the nut a as will be hereinafter morefully described, said flange being preferably formed in two sectionsdivided by a lf-shaped slot or notch 8, whereby, as will be clearlyunderstood, the entire flange may be bent over to engage the adjoiningside of the nut or the notch 8 receive one corner of the nut whereby theside walls of'the slot or notch 8 will. engage two sides of the nut, thelatter being securely held against turning in either event. It will, ofcourse, be understood, that the number of sides and the size of the nutwill govern the practice as to whether or not the entire flange willengage the nut or merely the two sections thereof, which are defined bythe intermediate notch 8.

(lo-acting with the base plate 5 is a washer 9 which is also formed withan opening 10 whereby it may he slipped upon the threaded end of thebolt 1, before the nut 4: is applied thereto, said washer beingpreferably bowed, as shown, and being formed of spring steel or similarsubstance or material, whereby it will at all times exert a pressureagainst the nut and thereby co-act with the base plate 5 in preventingthe nut from turning. It is to be particularly noted that the washer 9is formed on one edge. with a flange 11 which in the applied position ofthe parts is disposed opposite to the flange 7 hereinbefore referred toand which, when the parts are arranged as illustrated in Fig. 1, isintended to engage the base of the fish plate, whereby it will beprevented from turning and to also engage the adj oining edge of thebase plate 5, whereby all liability of the parts being turned will beprecluded.

It is to be understood that our invention is not limited. for use inconnection with fish plates, angle bars, and the like. For example, asillustrated in Fig. at, it may be used in connection with the block orbar which is bolt-ed between the rails at a frog or the like, said barbeing designated by the numeral 12. When the parts are applied to thisdevice, the flange 11 not only engages the adjoining edge of the baseplate 5, but is designed to extend over one side of the bar 12 wherebyit will. be securely held from turning.

It is further to be understood, that when the device is used inconnection with work which consists of wood, the flange 11 will beembedded in the wood, whereby it will be prevented from turning.

In the practical operation or use of our improved nut lock, the baseplate 5 and washer 9 are applied to the threaded end of the bolt, beforethe nut 4 is applied to the latter, and after the nut has been screwedup to the desired extent, the flange 7, is engaged therewith, as clearlyillustrated in the drawing.

Preferably the washer 9 is formed at one side with a split or slotcommunicating with the opening 10 and at one side of this slot, as bestillustrated in Figs. 1 and 3, the metal is turned outwardly. By thisconstruction and arrangement of the parts the washer 9 has greatlyincreased spring property and will stand great pressure without breakingdown and without losing its function or purpose as a spring. Hence itwill be seen that by this construction all wear on the nut or otherparts and the expansion of the bolt will be taken up and compensatedfor, all rattling prevented and the nut will be securely held inposition as long as de sired.

lVhile the accompanying drawing illustrates what we believe to be thepreferred embodiment of our invention, it is to be un derstood that theinvention is not limited thereto, but that various changes may be madein the construction, arrangement and proportion of the parts Withoutdeparting from the scope of the invention as defined in the appendedclaims.

What is claimed, is:

1. A nut lock comprising a base plate formed with anopening by which itis copies. of this patent may. be obtained for five cents each, byaddressing'tlie .1 Commissioner at Patents,

2. A nut lock, comprising a base plate formed with an opening by whichit is adapted to he slipped over the threaded end of a bolt, said baseplate being provided at one end with a flange for engagement with thenut, and a washer provided with an opening whereby it may also beslipped over the bolt, said washer being designed to have one edgereceived underneath the flange and being provided at its. other edgewith a flange engageable with the adjoining edge of the base plate, andto be embedded in the work when made of wood.

3. The combination with a bolt and nut screwed thereon, of a base plateformed with an opening through which the bolt extends, said base platebeing located back of the nut and formed with an outwardly and returnedflange engaging the nut, and a bowed washer or spring material mountedupon the bolt back of the nut, one edge of said washer extending behindthe flange and engaged thereby and the other edge of the washer beingformed with an inturned flange engaging the adjoining edge of the baseplate, and the work.

4. The combination with abolt and nut screwed thereon, of a base plateformed with an opening through which the bolt extends, said base platebeing located back of the nut and formed withan outwardly and returnedflange engaging the nut, and a bowed washer of spring material mountedupon the bolt back of the nut, one edge of said washer extending behindthe flange and engaged thereby and the other edge of the washer beingformed with an inturned flange engaging the adjoining edge of the baseplate and the work, said washer being formed at one side with a slot andthe metal at one side of the'slot being turned outwardly to form aspring tongue whereby in creased resilience will be imparted to thewasher to a maximum degree.

In testimony whereof we allix our signa tures in the presence of twowitnesses.
